[0020] As Figures 1-5 shown, an adjustable-angle liquid crystal display proposed in an embodiment of the present utility model includes: a bracket 1;

[0021] a rotating frame 2, the rotating frame 2 is rotatably installed on the bracket 1, and a driving assembly 3 for driving the rotating frame 2 to rotate is installed on the bracket 1;

[0023] a rotating assembly 8, the rotating assembly 8 is installed on the mounting plate 6 and is used for driving the display body 7 to flip and adjust the angle; the rotating assembly 8 includes two semi-circular plates 81 fixedly installed on one side of the mounting plate 6, a connecting plate 82 is rotatably installed on one side of the two semi-circular plates 81, the connecting plate 82 is fixedly connected with the display body 7, a rotating rod 83 is rotatably installed between the two semi-circular plates 81, a positioning gear 84 is fixedly sleeved on an outer surface of the rotating rod 83, a forward and reverse motor 85 for driving the rotating rod 83 to rotate is fixedly installed on one side of the semi-circular plate 81, a semi-toothed plate 86 is fixedly installed on one side of the connecting plate 82, and the positioning gear 84 meshes with the semi-toothed plate 86.

[0024] an adjusting assembly 9, the adjusting assembly 9 is installed on the rotating frame 2 and is used for driving the adjusting plate 4 to move along its sliding track.

[0025] The bracket 1 serves as the base of the entire display and provides stable support. The rotating frame 2 is installed on the bracket 1 and is rotated by the driving component 3. The driving component 3 can be an electric motor or other forms of driving devices, which is used to control the rotation of the rotating frame 2 on the horizontal plane. The adjusting plate 4 is slidably installed on one side of the rotating frame 2, allowing the display body 7 to be adjusted in height and angle in the vertical direction. A rotating motor 5 is fixedly inserted on the adjusting plate 4, and the rotating motor 5 is responsible for driving the display body 7 to rotate. The existing display screen content can be rotated. For example, when swiping short videos, the rotating motor 5 can be used to drive the display body 7 to rotate for vertical viewing. The output end of the rotating motor 5 is connected to a mounting plate 6, and a display body 7 is installed on one side of the mounting plate 6. The flipping and adjusting angle of the display body 7 is controlled by the rotating component 8. The rotating component 8 includes two semi-circular plates 81 fixedly installed on one side of the mounting plate 6. A connecting plate 82 is rotatably installed on one side of the two semi-circular plates 81. The connecting plate 82 is fixedly connected to the display body 7. A rotating rod 83 is rotatably installed between the two semi-circular plates 81. A positioning gear 84 is fixedly sleeved on the outer surface of the rotating rod 83. A forward and reverse motor 85 is fixedly installed on one side of one of the semi-circular plates 81. The forward and reverse motor 85 is used to drive the rotating rod 83 to rotate. A semi-toothed plate 86 is fixedly installed on one side of the connecting plate 82. The semi-toothed plate 86 meshes with the positioning gear 84. The flipping action of the display body 7 is realized through the meshing transmission of the semi-toothed plate 86 and the positioning gear 84. The adjusting component 9 is installed on the rotating frame 2 and is used to control the movement of the adjusting plate 4 along its sliding track to further adjust the height and angle of the display. When it is necessary to horizontally move the display body 7, the rotating motor 5 is started to drive the rotating frame 2 to rotate 90°. Then, by operating the adjusting component 9, the user can adjust the left and right horizontal position of the display body 7 according to needs. This device greatly increases the adjustment range of the display body 7 and improves the user's viewing effect.

[0026] As Figure 4 shown, in some embodiments, the driving component 3 includes a driving motor 31 fixedly installed on one side of the bracket 1. The output end of the driving motor 31 is fixedly installed with a first bevel gear 32. A second bevel gear 33 is fixedly installed on one side of the rotating frame 2. The first bevel gear 32 and the second bevel gear 33 are meshed with each other.

[0027] The driving motor 31 is fixedly installed on one side of the bracket 1. As the power source, it is responsible for providing the torque required for rotation. The first bevel gear 32 is installed at the output end of the driving motor 31 and is directly connected to the rotating shaft of the driving motor 31, converting the rotational motion of the motor into the rotation of the bevel gear. The second bevel gear 33 is fixedly installed on one side of the rotating frame 2 and meshes with the first bevel gear 32 to form a gear linkage. When the driving motor 31 starts and rotates, the first bevel gear 32 rotates accordingly, and the power is transmitted to the second bevel gear 33 through gear meshing. Due to the meshing relationship of the two bevel gears, the rotation of the second bevel gear 33 causes the rotating frame 2 to rotate. This design allows the rotating frame 2 to rotate at multiple angles on the horizontal plane, so that the display body 7 can be adjusted to the best viewing angle according to the needs of the user.

[0028] As Figure 2 shown, in some embodiments, a sliding plate 10 is fixedly installed on one side of the connecting plate 82, and a sliding groove is formed on the semi-circular plate 81. One end of the sliding plate 10 is slidably installed in the sliding groove.

[0029] The sliding plate 10 can move along the sliding groove on the semi-circular plate 81, thereby driving the display body 7 on the connecting plate 82 to rotate. The sliding groove restricts the moving range of the sliding plate 10, thereby restricting the rotation angle of the display body 7 on the connecting plate 82. The arc range of the sliding groove is the same as the rotation angle range of the display body 7, thereby stabilizing the angle rotation of the display body 7.

[0030] As Figure 4 shown, in some embodiments, the adjusting assembly 9 includes an adjusting screw 91 rotatably installed between the top and bottom of the inner wall of the rotating frame 2. An adjusting motor 92 for driving the adjusting screw 91 to rotate is fixedly installed at the bottom of the rotating frame 2. A T-shaped plate 93 is slidably installed between the two sides of the inner wall of the rotating frame 2. One side of the T-shaped plate 93 is fixedly connected to the adjusting plate 4, and the T-shaped plate 93 is threadedly connected to the adjusting screw 91.

[0031] The adjustment assembly 9 includes an adjustment screw 91 rotatably mounted between the top and bottom of the inner wall of the rotating frame 2. The adjustment screw 91 is designed to be rotatable along its axis. A bottom of the rotating frame 2 is fixedly mounted with an adjustment motor 92, which is responsible for providing power to drive the adjustment screw 91 to rotate. An output shaft of the adjustment motor 92 is connected to the adjustment screw 91. By controlling the forward and reverse rotation of the adjustment motor 92, the rotation of the adjustment screw 91 can be achieved. A T-shaped plate 93 is slidably mounted between two sides of the inner wall of the rotating frame 2. The T-shaped plate 93 is designed to be slidable between two sides of the inner wall of the rotating frame 2 so as to move up and down. One side of the T-shaped plate 93 is fixedly connected to the adjustment plate 4, so that the adjustment plate 4 can move along with the movement of the T-shaped plate 93. At the same time, the T-shaped plate 93 is threadedly connected to the adjustment screw 91. When the adjustment screw 91 rotates, due to the helix angle of the thread, the T-shaped plate 93 will move linearly along the axis of the adjustment screw 91, thereby adjusting the moving position of the display body 7.

[0032] As Figure 4 shown, in some embodiments, a bottom of the bracket 1 is fixedly mounted with a rubber pad 11, and anti-slip lines are provided at a bottom of the rubber pad 11.

[0033] The rubber pad 11 is mounted at the bottom of the bracket 1. As a buffering and anti-slip material, the rubber pad 11 can absorb vibrations generated due to the weight of the display or external impacts, reducing damage to the placement surface. The bottom of the rubber pad 11 is designed with specific anti-slip textures, which increase the contact area with the ground and improve the friction coefficient, thereby providing good anti-slip effects on both smooth and uneven surfaces. Due to the elasticity of the rubber material and the design of the anti-slip lines, even when subjected to external forces or movement, the display can remain stable, preventing sliding or tipping over.

[0034] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to these embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
